Web development is dominated by dynamic languages, but surprisingly few compiled languages seem to make headway in this space. The Go programming language looks like it might change that, but other compiled languages remain quite niche.
I know many people baulk at the idea of running an "old" compiled language like C or Pascal, but these languages seem (to me) to remain extremely fast and very light on resource usage. Two qualities that feel a bit out of fashion in todays web programming environment.
